Avoid all usage which you consider to be beyond your capability

Fuel safety

Basic safety rules
Look around you: - To ensure that people, animals or other things cannot affect your control of the machine. - To make sure that none of the above might come into contact with the cutting equipment. Branches, twigs, stones, etc. should be removed from the lawn before you start to mow. Make sure the cutter does not hit foreign objects such as stones, roots or the like. This can make the cutter dull and bend the engine shaft. Never lift up the lawn mower or carry it around when the engine is running. If you must lift the lawn mower, rst switch off the engine and disconnect the ignition lead from the spark plug.

WARNING! Fuel and fuel vapour are highly inammable. Take care when handling fuel and engine oil. Bear in mind the risk of re, explosion and inhaling fumes.
Never refuel the machine while the engine is running. Always ensure there is adequate ventilation when refuelling and lling oil. Move the machine at least 3 m from the refuelling point before starting it.
Never start the machine: 3 If you have spilt fuel or engine oil on the machine. Wipe off the spill and allow the remaining fuel to evaporate. If you spill fuel or engine oil on yourself or your clothes. Change your clothes. If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.
Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground. Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.

8 English

The engine should be switched off when moving over ground that is not to be mowed. For example, gravel paths, stone, shingle, asphalt, etc. Never run with the machine when it is running. You should always walk with the lawn mower.
Pay particular attention when pulling the machine towards you during work.

Cutting height

The brake handle must never be permanently anchored in handle when the machine is running.
Shut down the engine before changing the cutting height. The cutting height can be adjusted in ve different steps, mm.
Follow the instructions above, but do not use a lawn mower in a situation where you cannot call for help in case of an accident.
Do not set the cutting height too low as there is a risk that the cutters might hit ground with unevenness.

Basic mowing technique

General
WARNING! Make sure that your hands and feet do not come near the cutting attachment when the engine is running.
Mowing slopes can be dangerous. Do not use the lawn mower on very steep slopes. The lawn mower should not be used on inclines greater than 30 degrees. On sloping ground you should work along the slope. It is much easier to work along a slope than it is to work up and down it. Branches, twigs, stones, etc. should be removed from the lawn before you start to mow. Never lift up the lawn mower or carry it around when the engine is running. If you must lift the lawn mower, rst switch off the engine and disconnect the ignition lead from the spark plug. Make sure the cutter does not hit foreign objects such as stones, roots or the like. This can make the cutter dull and bend the engine shaft. A bent axle gives imbalance and heavy vibration, which results in a great risk of the cutter becoming loose. If any foreign object is hit or if vibrations occur stop the machine immediately. Disconnect the HT lead from the spark plug. Check that the machine is not damaged. Repair any damage. Never mow more than 1/3 of the length of the grass. This especially applies during dry periods. Mow rst with the cutting height set high. Then check the result and lower to an appropriate height. If the grass is really long, drive slowly and mow twice if necessary.
